Intelligent Slime

The Intelligent Slime is a creature that spawns rarely within any biome found in the Overworld. Each time an Otherworlder is about to be spawned, a Shizue, Hinata or Intelligent Slime has a 10% chance to spawn instead if there are no other Shizue, Hinata or Intelligent Slime mobs within 100 blocks in each direction (forming a cube). Out of the three, it has a 50% chance to spawn. (5% chance total to replace an Otherworlder)

It cannot spawn in any secondary dimensions that are included within the Tensura mod.

When killed, it has a 10% chance to drop Predator if the player has no copying/plundering Skills and   if the player has such a skill. It also has a 10% chance of dropping Great Sage which can't be raised by the use of Analyst or skill-plundering Skills

To damage an Intelligent Slime, one will need to overcome its Physical Damage Immunity by attacking it with a weapon imbued with magicules (Demon Steel/Mithril/Orichalcum swords and Shizue's sword) or a Skill (not all skills seem to work)
